High-throughput evaluation of in vitro CRISPR activities enables optimized large-scale multiplex enrichment of rare variants.

Abstract excerpt

Previous high-throughput evaluations of CRISPR activities for a large number of target and guide RNA sequences were based on measuring insertion-deletion frequencies rather than cleavage efficiencies. Here we develop two high-throughput in vitro methods, Cut-seq1 and Cut-seq2, to evaluate Cas9 cleavage efficiency for tens of thousands, or even hundreds of thousands, of guide RNA-target pairs. These methods reveal...
